Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic product processing technology, specifically to a processing cooling device for plastic products. Background Technology
[0002] Plastics are high-molecular-weight organic compounds polymerized from low-molecular-weight organic compounds under certain conditions. They are mainly composed of synthetic resins and made with plasticizers, stabilizers, lubricants, and colorants as auxiliary materials. Plastics are plastic under heating or pressure, but retain their solid shape at room temperature. Due to their lightweight, durability, and ease of molding, plastics are widely used in the manufacture of various products.
[0003] Cooling is an important step in the plastic molding process. Its main purpose is to quickly solidify and shape the molten plastic in the mold, thereby obtaining a product with sufficient rigidity and dimensional stability. Cooling can reduce the residual pressure of the product, prevent the product from twisting, deforming or breaking during demolding, and also help the product to be demolded smoothly.
[0004] In existing plastic product processing cooling equipment, molten plastic products need to be cooled in molds during processes such as injection molding, extrusion, and blow molding. However, when existing cooling pipes cool the plastic products in the mold, they cannot continuously circulate and reduce the temperature of the fluid in the cooling pipes, resulting in an inability to maintain a constant temperature difference for cooling the plastic products. This often leads to sudden cooling in localized areas of the plastic products in the mold. Consequently, the plastic products cooled in the mold often deform and have dimensional deviations due to inconsistent cooling and shrinkage in different parts, further reducing the functionality of the subsequent plastic products. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a processing and cooling device for plastic products, comprising...

[0007] A curved cooling pipe is fixedly installed on the inner side of the cooling support plate, and a plastic placement plate is slidably inserted into the upper end of the cooling support plate.
[0008] A semiconductor cooler is fixedly installed at the center of one end of the cooling chamber.

[0015] 1.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] The present invention will be further described below with reference to the embodiments.
[0026] Example 1
[0027] Reference Figure 1-5This is the first embodiment of the present invention, which provides a processing cooling device for plastic products, including a cooling device body 1, a cooling support plate 2 fixedly installed on the inner side of the cooling device body 1 near the lower end, a curved cooling pipe 3 fixedly installed on the inner side of the cooling support plate 2, a circulating water pump 4 fixedly installed at the center of the rear end of the cooling device body 1, a cooling box 5 fixedly installed on the side of the rear end of the cooling device body 1 near the circulating water pump 4, a semiconductor cooler 6 fixedly installed at the center of one end of the cooling box 5, a plastic placement plate 7 inserted and fixedly installed at the upper end of the cooling support plate 2, a cooling air box 8 fixedly installed at the center of the upper end of the cooling device body 1, and two symmetrical cooling fans 9 fixedly installed on the inner side of the cooling device body 1 near the rear end.
[0028] The output end of the circulating water pump 4 is connected to the input end of the cooling box 5 and an inlet pipe is installed. The input end of the circulating water pump 4 is connected to one side of the curved cooling pipe 3 and an outlet hose 10 is installed. The output end of the cooling box 5 is connected to the other side of the curved cooling pipe 3 and an inlet hose 11 is installed. Sliding grooves 16 are symmetrically opened on both sides of the internal side wall of the cooling equipment body 1.
[0029] Two sliding blocks 17 are symmetrically fixedly installed at the center of both sides of the cooling support plate 2. The sliding blocks 17 are slidably installed inside the sliding groove 16. A rotating motor 18 is fixedly installed on one side of the cooling equipment body 1 near the lower end. A double threaded rod 12 is fixedly connected to the output end of the rotating motor 18.
[0030] When the plastic product processing cooling equipment is in use, the operator first opens the door at the front of the cooling equipment body 1, so that the plastic placement plate 7 can be inserted and placed on the top of the cooling support plate 2. After placement, the operator closes the door and then starts the circulating water pump 4 and the cooling chamber 5 at the same time. This connects the semiconductor cooler 6, which is electrically connected to the cooling chamber 5, to the power supply. Under the action of the power supply, a temperature difference is generated between the P-type and N-type semiconductor materials in the semiconductor cooler 6. The cold end absorbs heat and the hot end releases heat. The heat absorbed by the cold end is transferred to the hot end through the semiconductor material and then dissipated into the environment by the heat sink on the outer surface of the semiconductor cooler 6. In this way, the semiconductor cooler 6 can continuously absorb heat from the cold end and release it to the hot end and the environment, thereby achieving the cooling effect of the cooling chamber 5.
[0031] Since the curved cooling pipe 3 is connected to the cooling box 5 by a water inlet hose 11, and the hot water in the curved cooling pipe 3 is circulated and replaced by the circulating water pump 4 to keep the curved cooling pipe 3 at a constant temperature for cooling, the cooling air box 8 at the upper end of the cooling equipment body 1 is started simultaneously. The cooling air box 8 is equipped with a refrigeration circuit and a compressor. The compressor compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and releases heat to the environment through the condenser in the refrigeration circuit. A fan pump is installed at the port of the refrigeration circuit, so that the nozzles installed at the lower end of the cooling air box 8 release the cooled compressed air to the inside of the cooling equipment body 1 under the action of the fan pump.
[0032] Then, as the cooling air inside the cooling equipment body 1 comes into contact with the hot air from the plastic product, the cooling fan is activated. As the cooling fan 9 rotates its blades, the hot air from the plastic product inside the cooling equipment body 1 is blown out of the cooling equipment body 1, allowing the cold air inside the cooling air box 8 to come into contact with the plastic product. This ensures that the temperature inside the cooling equipment body 1 remains constant, thereby allowing the plastic in the plastic placement plate 7 to be cooled consistently and comprehensively. This ensures a constant cooling temperature during the cooling process, thus guaranteeing the quality of the plastic product, resulting in better cooling effect and facilitating the cooling and molding of the plastic product.
[0033] Example 2
[0034] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a double threaded rod 12 is rotatably installed through the inner side of the cooling equipment body 1 near the lower end of the cooling support plate 2. Nut seats 13 are symmetrically threaded on the outer side walls of the double threaded rod 12. Irregularly shaped snap-fit blocks 14 are symmetrically fixed at the lower center of the cooling support plate 2. A support rotating rod 15 is cross-connected between the nut seats 13 and the irregularly shaped snap-fit blocks 14. A rotating shaft is movably installed at the intersection of the two support rotating rods 15.
[0035] When the plastic products are processed and cooled using the cooling equipment, the rotating motor 18 is started first, causing the double threaded rod 12 to rotate. This, in turn, drives the two symmetrical nut seats 13 to close and disperse the adjusting support rods 15. By rotating the double threaded rod 12, the support rods 15 and the cooling support plate 2 are raised and lowered. This allows the cooling equipment body 1 to cool plastic placement plates 7 of different heights, avoiding the need to replace the cooling equipment with matching ones when plastic placement plates 7 of different heights are present, and further improving the applicability of the cooling equipment.
[0036] The remaining structure is the same as that in Example 1.
[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
